1) The layout for the python root directory for all platforms should be as follows:

stdlib = {base/userbase}/lib/python{pyversionshort} platstdlib = {base/userbase}/lib/python{pyversionshort} purelib = {base/userbase}/lib/python{pyversionshort}/site-packages platlib = {base/userbase}/lib/python{pyversionshort}/site-packages include = {base/userbase}/include/python{pyversionshort} scripts = {base/userbase}/bin data = {base/userbase} [...] I have talked with a number of people at PyCon, including Tarek and MvL. Nobody objected, and several thought it was a good idea. I admit that I didn't understand that lib/python{version} was also part of the proposal. I'm fine with the bin/ change, but skeptical about the lib change - this just adds a redundant level of directories on Windows. The installation will end up in c:\python33\lib\python3.3 which has the software name and version twice in the path. Do we really need this? We already have this. The only difference in this proposal is that we go from pyversionnodot to pyversionshort, i.e. from c:\python33\lib\python33

Right not, we (at least I) have .../python33/Lib/ .../python32/Lib/

to

c:\python33\lib\python3.3 Given that we already repeat it, isn't it better to be consistent?

But there is no repetition currently on Windows installations. I though you were just proposing to switch lib (lower-cased, and scripts renamed as bin, and pythonxx). So I do not think I yet understand what the proposal is and how it would be different from what I have now.
